copper‐catalyzed domino method for synthesis of isoquinolino[2,3‐a]quinazolinones has been developed using readily available, substituted methyl 2‐(2‐haloobenzamido)benzoates and nitriles as the starting materials. The domino process comprises an Ullmann‐type C‐arylation, intramolecular addition of NH with CN, and nucleophilic attack of amino to ester group. The inexpensive, convenient and efficient copper‐catalyzed
已经开发了一种铜催化的多米诺骨牌方法,用于合成异喹啉代[2,3- a ]喹唑啉酮,使用容易获得的取代的2-(2-卤代苯甲酰胺基)苯甲酸甲酯和腈作为起始原料。多米诺过程包括Ullmann型C芳基化,NH与CN的分子内加成以及氨基对酯基的亲核攻击。廉价,方便,有效的铜催化方法应为构建氮杂环化合物提供一种新的有用策略。
